Figure 6 is an enlarged detailv sectional View of the central portion of Figure 3 showing a modified construction. Figure 7 isa view similar to Figure 6 illustrating still another modification. Figure 8 isa view illustrative of still another modification from that shown in Figures 6 and 7,

In the drawings, my. improvements are shown as incorporated in connection with a so-called automobile car7 wherein very large door OpeningsV are vusually employed, said openings being adapted to be usually closed by two doors, one of saiddoors corresponding in size' to the average door openingof box cars and being usually employed only for normal service and the other of said doors being in the nature of an auxiliary door and utilized only when the exigencies of the service re'- 4quire large openings.

' The said auxiliary door is usually provided with a heavy door post On the interior of the door which may move with the door and which providesy a means for locking the door relatively to the car structure from the inner side of the car, said door post usually having associated therewith a wooden block 'adapted to receive the cooperating members which are applied when the car is used in grain service.

In said drawings 10-10 denote the vertical side door'posts of the usual door vopening in the side of the car, each said post having an angle-shaped sealing member 110 on the outerside thereof, the car being provided with a'channel side sill 11 reinforced adjacent the door opening by an angle member 12 and the a provided with an outer depending flange 17 is rigidly secured to a series of brackets 18 which are spaced lengthwise of the door.

Thetwo closure members are indicated at .Ap and BY respectivelyi,closure. A being the.

auxiliary door and closure B being the main or ynormally employed door. Each V'closure member has marginal reinforcing elements or members of generally Z-shape at the upper lhorizontaland rear vertical-margins, as indicated at 19 and`20, respectively. Each' ofY the upper horizontal. marginal elements 19 has therinner and outer flanges thereof, as

3 indicated at 21and 22, respectively disposed .in the inner and ouTI er planes ofthe door, the

.connecting webs 23 between theV said flanges defining substantially the depth of the door." The rear vertical marginal reinforcing elements 2O for each door are also formed vof Z-shapedrsection leach having an outer flange 24 disposed in alignment with the flange 22 of the upper' marginal member and the inner flange 25 is bent rearwardly in .the form vof a U shape 26 .adapted to. en-

close the associated sealing angle member 110 when the door is in closed position. The web 27 of the said rearfvverti'cal marginal element is preferably of thesame depth as'the web 23 of the upper horizontal marginal element 19. Y The frontverticalmargins of the respective doors A and B are reinforced by vertical "elements or members 28 and 29 said elements heilig of different construction for the respective doors, inasmuch as the element 28 of door A is adapted to overlap the element 29 on door B. Said marginal element 28 is preferably Y in thek form of a trough-shape having the base 3Q lying at the.k inner plane of the door, and vthe walls or 'side sections thereof, as, indicated at 31 and 32', extending outwardly therefrom toward lthe youter plane of the door, the. section 32 extending substantially at right angles to the door and having a flange 33 disposed substantially in the outer plane of the door, the outer end ofk said flange being preferably curved as indicatedat 34 for the purpose of presenting a flared guideway I within which the companion door Bis adapted toeXtend. f It will thus be noted thatthe said base'30, section 32. and flange 33 combine topresent a Z-shaped element at the meeting edge of the door. The section 31 is preferably disposed in an inclined position. relative to the base 30,.thus presenting a depression which isV of wider extent adjacent the outer surface. of the door than at the base thereof.

- The clement 29 on the companion doorB is said depending flange 43, by rivets 44,y is a facing plate 45. The VSpace.intermediate the facing plate and` plane` of the door is preferably filled by wood fillers 145. The door is reinforced on its inner sur- The main bodyv of plate A is lpreferably .l

downwardly, presenting a depending section aslindicated at 43, thus providing a substantially Z-shaped lower margin. inwardly of and secured thereto face by diagonal braces 46-46, saidfbraces being preferably of U-shape section, and extended across the meeting edgesof the upper and lower panels of the respectivedoors.

The pan-els 38 and 39 of door A at their forward. edges are deflected inwardly as indicated at 47, and are attached to the inclined flange 31 ofthe trough-shaped beam or reinforcing `element by rivets 48, the inclined relation of said flanges 47 and 31 permitting accessibility with reference to the rivets 48. Y

On the inner side of theV door A there isa door post C of usual construction, saidpost preferably consisting of an angular-shaped .member 50 having a flange llying against the inner face of the door, andsecured thereto by rivets 52, which extend through the base of the trough-shaped reinforcing element.

The member is connected to the inclined Wall 31 by braces 53, which are secured tothe .web 54 of the post 5() and the inclined section 31. Spacedy from each other. lengthwise of the beam or lelement 28, and disposed in theV trou h-shaped depression area series of spacing illers 55.. Said fillers are formed'with walls 56, 57 and 58 which are riveted to the respective side sectionsvand base of the depressed portion. of the door.V

The lower panels of the doors are formed of relatively heavy plates and the upper vpanels of somewhat lighter plate, the body of the upper plate being rigidified by suitable indentations or embossments which are designed to rigidify the plate on various crosslines.

The embossments are preferably made to present .identifying symbols or advertising symbols. In the present embodiment the door B is embossed with the monogram of a large railroad system as indicated by the rec-A tangular border 59, having the portion intermediate said border rigidiiied by embossed lettering 60. The sections of door' .plate adjacent the monogram are 'preferablyrein forced by meaningless embossments consisting of elongated corrugations 61 and triangular embossments 62. y y

The plate 38 of door A is shown by way of illustration as rigi-diiied by an embossnient descriptive of the railroads operations, said embossmentincluding acontinueus border' 62 V having curvedeorners 63, which at the lowerk corn'ersfare disposed substantially tangent f to the diagonal bracesflt, and the space intermediate said border isreinforced by embossed letteringl.'v

At theyrespective upper'Y and .lower overlapping corners ofthedoor Af there are disposed corneivcapsl-65 and whicligare ex- `tend-ed 'over theiadjacen-t door-B for the pui'- pose of sealing the crevices at the junction of Y said doors.

The'door E includes an outer marginal reinforcing ele- -ment^1-10v in the 'formxof a Z-shape,vwhich1 may be formed. either by pressing from a plate or from a Z-bar rolled shape, as may bey preferred. The main door plate as indicated at 111 is in the outer plane of the door and diverted inwardly by an inclined`r section 112 and thence in parallelism with and to overliethe inner' flange` of the outer member 110', as indicated at-ll. On the inlner `*face of the door there is disposed a door post f V11st of Z-shape,kriveted by one of its flan-gesto the Z-shaped element 110 and to `Vthe door plate by, rivets 115. The post member 1145 is further braced against the door :plate by braces 116. In the channel providedby the offset door plate and Z-shaped element there are disposed filler bracketsl117.

-The door F includes an outer vertical marginal-elementv y118 of channelshape havingunequal flanges 119 and 120 with the latter of greatery extentI andy disposed in the outer The body doork plate 121, which. is disposed in` theouter plane ofthe door, is secured to the wide flange 120 ofthe marginal element- 118by rivets 122, and a bracing filler l123 is vdisposedxon the inner side of the channel section 118 to brace lthe flanges l119 and 120etliereof.V In this arrangement it will be appreciated that a single row of rivets may c "be utilized tolsecure the fillers 123, the marginal element 118' and the plate 121 togetheiI rvas compared with the two rows utilized in the construction.-heretofore described.

The5 embodiment ofthe invention illustrated in Figure 7 discloses a construction` vsimilar'to Figure 6 with cooperating doors G and H but theV construction of the door -H corresponding generally to the door F is modified; -The door H includes channelshapedmarginal element 200 having unequal f ofthe front edge construction of thevdoors is indicated in Fign Aurei16';.-"In' thisv arrangement, the doors are flanges 201.1and 202 with the latter of wider .extent thanithe former andv disposed in the inner'plane of the door. Thebody of tlie door plate 203, which is disposed in the outer plane'of the door, is directed inwardlyjat -atufincline:asl indicated at 204, and thence in ,parallelism with flange 205 vof the channel meinber 200, 'alidfi'iveteclthereto by rivets l2065 SA- filler Ainember 207 is disposed in the i angle between the iianges of the channel n member 200.
